Don't have time for a long post.
I just finished all of Grant Morrison's X-Men (New X-Men, whatever) run.
I had read the first arc (114-116) a while ago, but just hadn't gotten around to the rest (117-154). Themes, ideas, characterization, were all very good. Plotting not so tight.
The final arc consisted of a story that would never happen because the characters got the Phoenix Force to basically prune them from the timeline. It all looked super-cool from our perspective, but from where those characters sit (Beak's grandson-never-to-be Tito, for instance) I doubt it would seem so hot.
Better than good art delivered throughout by (off the top of my head) Quitely, Kordey, Bachalo and Gimenez.
Bottom line, tons of fun, really enjoyed it.
